Hey Vaibhav,

To view the build log for a failed stack image:

1. Go to the Stacks Tab within the Cycle Portal
2. Select the Stack with the error
3. Select the specific Stack Build with the error
4. In the dialog, select the Images Tab
5. Find the Image with the error, and click the Build Log link in the far right

If the image itself does not yet exist, you won't be able to see the full build log, but if you hover over the failed state in the upper left of the Stack Build dialog, it may provide some insight into the error.

Thanks Bryce

Happy to help!
